Hello Forum,
i started to connect my Arduino to Home Assistant using MQTT protocol.
I have to pass some parameters defined with input-number integration to Arduino then I create a button on the front end with the following code:
type: button
tap_action:
action: call-service
service: mqtt.publish
service_data:
topic: Hassio
payload: '{{ states.input_number.box1.state | int }}'
The issue i am founding is that the payload is not the number of the input_number but it’s a string containing “{{ states.input_number.box1.state | int }}”.
What i did wrong?
Thanks in advance
Alessandro
